Brief Summary

Aim of the study is to evaluate postoperative analgesic effect of ultrasound guided PENG block in comparison to ultrasound guided caudal epidural anaesthesia for hip surgeries in paediatrics

Detailed Description

Hip surgeries in paediatric patients such as open hip surgery for correction of developmental dysplasia of the hip (DDH) lead to extensive injuries and severe pain. Multimodal analgesia is required to provide intraoperative and postoperative analgesia and to prevent the undesirable side effects of opioids including sedation, nausea, vomiting and constipation.

Perioperative pain control is of paramount importance during paediatric hip surgery. Inadequate analgesia can contribute to patient and parental dissatisfaction, prolonged recovery, and increased length of hospital stay. As such, regional anaesthesia is advantageous in providing sufficient analgesia while reducing the adverse effects of opioids. The use of regional anaesthesia in the paediatric population has increased over the last decade as it offers several potential advantages in the provision of postoperative analgesia including a reduction in parenteral opioids, decreased exposure to general anaesthetic agents, and shortened hospital stay. Such techniques may be particularly valuable following painful orthopedic procedures including hip and femur surgery.

Neuraxial techniques (caudal and intrathecal), lumbar plexus blockade, and combined femoral nerve and fascia iliaca blockade have been shown in a myriad of paediatric studies to exhibit opioid-sparing effects and lower postoperative pain scores in patients who are suffering from hip pain.

Caudal block is a common technique used for perioperative pain relief in paediatric lower limb surgeries but despite the success of neuraxial blocks in decreasing postoperative pain scores in paediatric patients undergoing hip surgery, positioning requirements, bilateral sensory and motor blockade, and urinary retention limit their use.

Among peripheral nerve block techniques used for relieving pain associated with hip fracture, ultrasound-guided femoral nerve (FN) block, fascia iliaca compartment (FIC) block and 3-in-1 FN block are widely used. However, these techniques have often failed to provide adequate block of the obturator nerve (ON) and the accessory obturator nerve (AON).

The pericapsular nerve group (PENG) block is an ultrasound guided approach, first described by Girón-Arango et al.(11) in 2018 for the anaesthetizing the articular branches of the femoral, obturator and accessory obturator nerves that provide sensory innervation to the anterior hip capsule. It is a plane block involving one injection, performed under ultrasound guidance, of a high volume of local anaesthetic into the musculofascial plane between the psoas tendon anteriorly and the pubic ramus posteriorly. It was suggested that the articular branches of ON were blocked successfully due to the proximity of the target area to the subpectineal plane.

PENG block has been initially used as an alternative regional anaesthetic technique for the management of acute pain after hip fracture , but its applications are expanding, suggesting a potential role for analgesia after elective hip surgery. Previous studies concluded that this technique could provide an effective blockade of the articular branches of FN, ON and AON, with a potential motor-sparing effect.
